This report summarizes the activities and findings of YVO during the year 2020, focusing on the Yellowstone volcanic system. Highlights of YVO research and related activities during 2020 include an active-source seismic experiment to image the top of Yellowstone\u2019s magma reservoir; semipermanent Global Positioning System array deployment, including a new site near Mary Mountain; studies of hydrothermal activity in the southwest portion of Yellowstone National Park; numerous geological studies, including characterization of hydrothermal explosion craters, updating existing maps, and refining the ages of Yellowstone volcanic units; investigation of a dormant period at Old Faithful Geyser that may be related to regional drought 800\u2013650 years ago, and development of a publicly available online map interface.Steamboat Geyser, in Norris Geyser Basin, continued the pattern of frequent eruptions that began in 2018 with 48 water eruptions in 2020, matching the record for a calendar year that was set in 2019. Giantess Geyser, in the Upper Geyser Basin, erupted for the first time in 6 years in August 2020 and experienced a second eruption in September. Patterns of both seismicity and deformation in 2020 were similar to those in 2019. Deformation patterns during 2020 showed trends that were similar to previous years. Overall subsidence of the caldera floor, ongoing since late 2015 or early 2016, continued at rates of a few centimeters (1\u20132 inches) per year, and minor subsidence of Norris Geyser Basin that began in 2018 slowed during 2020 and stopped by the end of the year. Throughout 2020, the aviation color code for Yellowstone Caldera remained at \u201cgreen\u201d and the volcano alert level remained at \u201cnormal.\u201d", "description": "v, 44 p.", "publisher": {"@type": "Organization", "name": "U.S. Geological Survey"}, "author": [{"@type": "Organization", "name": "Yellowstone Volcano Observatory"}], "funder": [{"@type": "Organization", "name": "Volcano Science Center", "url": "https://www.usgs.gov/centers/volcano-science-center"}], "spatialCoverage": [{"@type": "Place", "additionalType": "country", "name": "United States", "url": "https://geonames.org/6252001"}, {"@type": "Place", "additionalType": "state", "name": "Idaho", "url": "https://geonames.org/5596512"}, {"@type": "Place", "additionalType": "state", "name": "Montana", "url": "https://geonames.org/5667009"}, {"@type": "Place", "additionalType": "state", "name": "Wyoming", "url": "https://geonames.org/5843591"}, {"@type": "Place", "additionalType": "unknown", "name": "Yellowstone Plateau", "url": "https://geonames.org/5687470"}, {"@type": "Place", "geo": [{"@type": "GeoShape", "additionalProperty": {"@type": "PropertyValue", "name": "GeoJSON", "value": {"type": "FeatureCollection", "features": [{"type": "Feature", "properties": {}, "geometry": {"type": "Polygon", "coordinates": [[[-111.170654296875, 44.06390660801779], [-109.79736328125, 44.06390660801779], [-109.79736328125, 45.09097463835656], [-111.170654296875, 45.09097463835656], [-111.170654296875, 44.06390660801779]]]}}]}}}, {"@type": "GeoCoordinates", "latitude": 44.57744062318717, "longitude": -110.4840087890625}]}]}
